MVB设备控制器的发送模块设计

列车通讯网络广泛应用于高速列车。然而其核心技术——多功能总线控制器技术被外国公司掌握,这大大限制了高速铁路技术在我国的发展。论文介绍了多功能总线控制器编码器的设计,编码器有六个模块组成,分别为位控制单元、FIFO单元、帧分界符单元、数据转换单元、CRC校验单元和曼彻斯特编码单元。

Design of Multifunction Vehicle Bus Controller Encoder

The Train Communication Network(TCN) is widely used in high-speed train,However,its core technology:Multifunction Vehicle Bus Controller(MVBC) is owned by foreign companies,which limits the development of high-speed railway in China.The paper describes the design of encoder which is divided into seven modules: bit control unit,FIFO unit,frame delimiter unit,data conversion unit,CRC unit,Manchester encoding unit.
